Abstract

The invention relates to a combustion engine, in particular to a general-purpose high-speed engine, comprising a crankcase, a cylinder block and a cylinder head connected in sequence, a crankshaft mechanism, a gas distribution mechanism, a power generation structure, a lubricating structure and a cooling structure, the crankshaft mechanism It includes a crankshaft and connecting rods, the crankshaft is installed in the crankcase, the cooling structure includes a magneto, a cooling fan and an air guide cover, the magneto is installed outside the crankcase, and the output end of the magneto is connected to the cooling fan. The cooling fan and the cylinder block are located in the air guide cover, wherein the valve train includes camshafts, cams, rocker arms, intake valves and exhaust valves; the power generation structure includes flywheels, permanent magnets and stators; the lubrication The structure includes an oil pump, an oil inlet passage, an oil outlet passage and an oil outlet hole. The structure of the general-purpose high-speed engine of the present invention is relatively simple, the overall volume is small, so it is convenient to carry, and the crankshaft speed is higher.

Description

technical field [0001] The invention relates to a combustion engine, in particular to a general-purpose high-speed engine. Background technique [0002] General-purpose small gasoline engine is a kind of motor tool equipment, referred to as general machine, referring to gasoline engines other than those used for vehicles and special purposes, and its rated power is generally below 30kW. It is mainly used as supporting power for agricultural and forestry plant protection machinery, small agricultural machinery, garden machinery, generator sets, construction machinery, outboard machinery, etc. Because of its small size, light weight, low price, and convenient use, the general-purpose small gasoline engine occupies an important position in various machine tools. Especially among the knapsack machines, the general-purpose small gasoline engine is the only supporting power. The general-purpose small gasoline engine is the same as the general internal combustion engine, has a ba...
